Ever wonder how the water draining down your sink gets clean again? Think about it: The water you use to clean your dishes is the same water that runs through the toilet. There is only one water pipe to the house, and that source provides water for the dishwasher, tub, sink, washing machine, toilet, fish tank, and water filter on the front of your fridge. And there’s only one drain from your house, too! How can you be sure what’s in the water you’re using?

    No, kinetic sand won’t work for this experiment because it is coated with a polymer. It is important to use plain sand.

    Will kinetic sand work as play sand is very expensive?
